At what cost is efficiency, when the air you breath is polluted by fossil fuel burning vehicles.
Would you drive a safe inefficient car that did not pollute the atmosphere you breath.
Google MDI compressed air cars and see what this French company is trying to do. Its not a long distance design at the moment however development could solve these problems. " Get behind the compressed air car and you'll maybe breath"

What effect if any does this energy transfer have on the overall efficiency of the car engine?
As a "heat engine", a car engine must rid itself of heat to continue. Efficiency of the heat engine depends on the difference in temperature; therefore, as the temperature outside reaches the temperature inside, the engine stops.
How much does car petrol cost per 1 km?
That depends on the size and efficiency of the car/engine.
Does it affect the car if you put either unleaded or leaded petrol in a car?
It can effect engine performance and fuel burning efficiency.
What is the purpose of a expansion box on a car?
It increases engine power and also increases fuel efficiency.
What is the efficiency of a car's engine when he input is 20000 joules and the waste heat is 15000 joules?
The efficiency of the car's engine is calculated by dividing the useful energy output by the energy input. In this case, the useful energy output would be 5000 joules (20000 input - 15000 waste heat), thus the efficiency would be 5000/20000 = 0.25 or 25%.
How many kilometer in 1 liter consume by 3.2 diesel engine?
The fuel efficiency of an engine will depend on the car itself, amongst other factors.
What is a specific example of a machine and describe how its mechanical efficiency might be calculated?
An example of a machine is a car engine. Mechanical efficiency can be calculated by comparing the work output (such as the power produced by the engine) to the work input (such as the energy from the fuel). The formula for mechanical efficiency is: Efficiency = (useful work output / total work input) x 100%.
Can your car function without a thermostat?
it can start but it won't go far as the engine will "explode" because of the increase of temperature. A thermostat regulates the temperature system of your car.. Usually the engine will run too cold with out a thermostat. That will hurt the efficiency of the engine.
The efficiency of a car depends on the weight of the car?
Efficiency(weight), or E(w)
What is the efficiency of a gasoline engine?
Gasoline engines have a 30% efficiency, as compared to a Diesel engine having 40% efficiency. COOL HUH
What connects the transmission to the engine in a automatic transmission car?
A torque converter. And usually a clutch as well, for better fuel efficiency.
What is the efficiency of a car's engine when the heat input is 100000 joules and the waste heat is 75000 joules?
25%
